WebMay 1, 2013 · With quality-guided methods, every pixel on the phase maps is associated with a quality value, which measures the smoothness of the pixel in contrast to its surrounding ones. The unwrapping process starts from the pixel with the highest quality and continues to the lower quality ones until all pixels are unwrapped. WebSep 25, 2024 · USE Currently, although others may be added in the future, there are only two algorithms supported: a quality-guided single wavelength unwrapping algorithm, and a double wavelength algorithm. These commands are found in "Plugins > DHM Utilities > Phase Unwrapping".
http://fastnfreedownload.com/ WebOct 1, 2024 · With the quality index, iterative phase unwrapping is performed with strategies of flooding-fill [ 19] or region-growing [ 20 ]. In each round, the pixel with the best quality is found and unwrapped. With the quality as guidance, pixels with error-prone phases are processed last, and thus alleviate or remove error propagation.
